In the Korean comments

These are 15 Korean-language comments, listed highest-liked first, from a video that had 691 comments when they were collected. They were picked because they contain Hangul, so nothing here says who wrote them. Eight of the 15 use 채원희 (Chaewonhee, the fan pairing name for the two), including the top comment, which reads, in translation, "Ah, so cute, Chaewonhee." Four call the pair round: one comment says "round sisters" and another "the two circles." Two others go beyond a compliment. One reads, in translation, "I like that every time they do a challenge, they hug the same way at the end." The other reads, "Let's make a unit out of you two, you're both so cute." All 15 are affectionate, and nobody in this sample criticizes or disagrees.

What the words mean

Taken apart, 채원희 (Chaewonhee) is 채원 (Chaewon) plus 원희 (Wonhee), overlapping on the shared syllable 원 (won). It is a fan-made pairing name for the two, not one person's name. The register is fan shorthand and affectionate. 동글동글 (donggeul-donggeul) literally means "round and round." Said of a person, it is an affectionate description of soft facial features and a lovable image, not a remark about body shape. The register is fond and cute.
